Product Detail

Description:
JW5 series high voltage grounding switch is composed of three single poles and operating mechanism. Each single pole consists of a base, a pillar insulator and a conducting rod. The conductive rod is installed on the base, and the static contact is installed on the top of the pillar insulator.
The operating mechanism drives the conductive rod to rotate upward from the horizontal position through the transmission element, and is stuck or inserted into the static contact to realize the closing of the ground switch, and the opening process is the opposite.

Main Features:

  • The product structure is simple and reasonable, easy to assemble, transport, install and debug.

  • The conductive rod is made of high-strength alloy profiles with good electrical conductivity, high mechanical strength, light weight, strong anti-corrosion ability and long service life.

What is the working principle of the indoor high-voltage AC grounding switch?

During normal operation, the grounding switch is in the open position, not affecting the normal operation of high-voltage electrical equipment. When maintenance of the high-voltage electrical equipment is required, the relevant power sources are first disconnected. Then, the grounding switch is closed through the operating mechanism, connecting the conductive parts of the equipment to be maintained reliably to the grounding network. This action ensures that any residual charge on the equipment is safely discharged to the ground, preventing the risk of electric shock to maintenance personnel when they come into contact with the equipment.

How does a transformer work?
Transformer Operation PrincipleA transformer is an electrical device that operates on the principle of electromagnetic induction to transfer electrical energy from one circuit to another. It enables the adjustment of voltage levels within an alternating current (AC) system, either stepping up (increasing) or stepping down (decreasing) voltage while maintaining the same frequency.Working Principle:Basic ComponentsA transformer consists of two coils, known as windings—the "primary winding" connect

Constant testing of high-voltage cable lines
1. Definition of High-Voltage Cable Line Constant TestingHigh-voltage cable line constant testing refers to the systematic measurement, using specialized instruments, of electrical parameters such as resistance, inductance, capacitance, and conductance before a cable line is commissioned or after major maintenance. The aim is to obtain fundamental data characterizing the electromagnetic properties of the cable, serving as a critical testing phase that provides accurate parameter support for powe

Withstand voltage test of high-voltage cables
Withstand voltage test is an insulation test, but it is a destructive test that can reveal insulation defects difficult to detect in non-destructive testing.The test cycle for high-voltage cables is three years, and it must be conducted after non-destructive tests. In other words, the withstand voltage test is performed only after all non-destructive tests have been passed.Most high-voltage cables used today are cross-linked polyethylene (XLPE) cables, which can have large cross-sections and cov

I. Introduction to Cable Grounding Loop CurrentCables rated 110 kV and above use a single-core structure. The alternating magnetic field generated by the operating current induces a voltage on the metallic sheath. If the sheath forms a closed circuit through the earth, a grounding loop current will flow on the metallic sheath. Excessive grounding loop current (loop current exceeding 50 A, more than 20% of the load current, or a ratio of maximum-to-minimum phase current greater than 3) not only a
